CFMX fails to respond under high load with IIS5
Gentle peoples, We still have this problem .. CFMX crashing when it's being worked. thought it was wddx, but it's not wddx .. see http://webforums.macromedia.com/coldfusion/messageview.cfm?catid=7threadid=586790 http://webforums.macromedia.com/coldfusion/messageview.cfm?catid=7threadid=586790 for reference but in short .. If you fill up the activeHandlerThreads to max under IIS then you are guaranteed to crash the server.. create a page that takes some time to return results .. nothing big .. say 900ms or so.. and hit it as fast as you can.. have cfstat running and watch it come down .. This is not very good.. The server listening on port 8500 (native http server) still purrs. so it's as if IIS / CFMX communication is failing .. can someone else please verfiy this .. what about settings, should we put the activeHandlerThreads to up above a few thousand ? cheers -Original Message- From: Buckland, Ramon [mailto:[EMAIL PROTECTED] Sent: Friday, 21 March 2003 5:40 PM To: CF-Talk Subject: RE: CFMX crashes with high load on cfwddx Thanks Joe, I've googled and searched a good deal, and only found this relevant one http://www.houseoffusion.com/cf_lists/cache/4/19/19054.htm http://www.houseoffusion.com/cf_lists/cache/4/19/19054.htm Is this it ? As far as I can see, what i am experiencing is very simlar, though slightly worse as this actually stops the server from responding altogether not poor performance, rather no performance ;). bit of an opener for Denial of Service attacks no ? ie: If I know a webserver uses a cfwddx and runs CFMX then .. a constant hit, and down it comes.

RE: Learned something today (Oracle)
Tony, My guess is that there is an index on the orderno field but it is a 'varchar' index (as it should be) because the string you are comparing to is an int, it's probably converting each orderno to int and comparing that way. (I would think the opposite though) so because there is no, 'int' index for that column, then it table scans. just a punting guess. -Original Message- From: Tony Schreiber [mailto:[EMAIL PROTECTED] Sent: Thursday, 3 April 2003 8:58 AM To: CF-Talk Subject: Learned something today (Oracle) I couldn't understand why some queries on tables selecting using the primary key (orderno) was taking so long...

T-SQL is Transact SQL, (it originated from Sybase) Sybase (before they sold their technology to Microsoft to make Microsoft SQL Server) also called their server SQL Server After the sale, Sybase then changed it's name, so to not confuse anyone (potentially) MS-SQL (MSSQL) is of course Microsoft SQL Server and is named such (by others, i don't think Microsoft calls it that) Sybase is still Sybase, but of course has the products ASE and ASA (Adaptive Server Enterprise and .. ..

RE: Cookies and browser launch methods
Bryan, The tricky detail in your scenario is the non-persistent cookie. (See note at bottom for details on persistant/non persist cookies) Now, when you launch a New browser via CTRL+N, it gets a copy of ALL the vars in memory at that time from the original (including your non persistant cookie). However, when you launch a new browser via the link, it will open up a new instance in it's own memory space and thus does not have the cookie existing. The reason for the 'Taskbar' 2nd browser not running in the same memory space as the first two is probably due to the little tick box on the shortcut which says 'Run in seperate memory space'. (Win2k, if it's not Win2k .. then ask Microsoft :-) If we wanted a web application to be able to have mulitple logins from the same workstation, I would use a seperate cookie name. side note As you know, when the cookie is persistent, it is stored on disk, for all and any instances of that browser to see. So if you closed a browser (and the cookie didn't expire, and the session didn't expire) and opened a new browser within the session/cookie timeframe, then you will of course get the existing session. /side note hope that helps, I may be off is some places (all ?) but from what i can tell and my experience this fits the bill. cheers Ramon Buckland -Original Message- From: Bryan Stevenson [mailto:[EMAIL PROTECTED] Sent: Thursday, 3 April 2003 8:53 AM To: CF-Talk Subject: Cookies and browser launch methods Hey All, I've just bumped into a situation I haven't seen before and am wondering if anyone can explain why this happens. The Situation: A site that uses a sessions table in the DB and stores the session ID in a non-persistent cookie once the user logs in. The site is colour coded based on the user's group. If I open a browser and login as a user of group A and then use CTRL+N to launch a new window and login as a user of group B, the second login logs me in as the first user. Now that's not odd, because the cookie's name is the same no matter what user group, so what happens when I log in as the second user is the security routine is bypassed (because the cookie already exists from the first user login) and the app continues as if the first user was logged in. Now for the weirdness. If I do the same as above EXCEPT I don't use CTRL+N to open a new windowI use the IE icon in my taskbar. When I do that and log in, I do get logged in as a user of group B (different colour scheme shows). So what is the difference where cookies are concerned when launching a new window via CTRL+N or from the taskbar? Clearly there is some sort of seperation when launching from the taskbar, so if anyone can explain it (and provide a solution) that would be great. I could of course have different cookie names for different user groups (which I may do anyway), but I'd really like to understand what's going on. BTW this has happened in IE 5.5 and 6 TIA Cheers Bryan Stevenson B.Comm. VP Director of E-Commerce Development Electric Edge Systems Group Inc. t. 250.920.8830 e.

Hi Costas, IE if told to accept a cookie, will accept it from whereever it comes (banner ads)(think doubleclick.com) frames ..

The app works fine on my dev box but when deployed to the production box has a strange problem with numerical fields. Its running CF4.5 with SQL Server 7. All numerical fields are being returned in the format 99,999.00 - notwithstanding the problem, applying NumberFormat fixes it but that doesn't actually solve the problem as to why they are being returned this way. Unfortunately applying NumberFormat to numbers used in queries and lists really screws with the application. The other interesting effect is that if the app is doing a query to a field with an ID greater than 999 it falls over because of the comma inserted into the number. For example doing a query to row 16123 return row 16 not row 16123, because the query string displays the row ID as 16,123.00.

I added z-index more for demonstration - The issue is - that you can overalp content. Unlike using an include - that will put it at the bottom no matter what - you will need to scroll to get content beyone viewable screen -but footer will hang on to the bottom edge. Use it carefully because there are almost always some trouble spots. IF your footer can overlap content - not a biggie.

CF can only timeout a thread/request that it has control over - if it's given control of the thread to a another source (database, COM, CFX, etc) then it must wait until that source returns control to it before it can time out the thread. That fact that CF isn't timing out leads me to believe that it not in control (or that it's just plain toast - but since you say that JRUN is still queueing requests it seems to be working).

RE: CFMX crashes with high load on cfwddx
Thanks Joe, I've googled and searched a good deal, and only found this relevant one http://www.houseoffusion.com/cf_lists/cache/4/19/19054.htm Is this it ? As far as I can see, what i am experiencing is very simlar, though slightly worse as this actually stops the server from responding altogether not poor performance, rather no performance ;). bit of an opener for Denial of Service attacks no ? ie: If I know a webserver uses a cfwddx and runs CFMX then .. a constant hit, and down it comes. As an example, one of the pages being converted from 4.5 to MX has 3 CFWDDX calls on the one page. I only have to generate a burst of 3-5 seconds on a freshly rebooted server and MX dies. If there is no fix, we are a bit worried about this as the site has over 250 references to cfwddx (was a fundamental design to the site). ?help :-) -Original Message- From: Joe Eugene [mailto:[EMAIL PROTECTED] Sent: Friday, 21 March 2003 4:15 PM To: CF-Talk Subject: RE: CFMX crashes with high load on cfwddx Found I can bring down our MX server where cfwddx is used.

bug (maybe) with evaluate() and CFMX
This works in CF4.5 but not in CFMX.
(Can't test for CF5)
evaulate only takes one 'expression'.
You can't combine multiple expressions seperated by ; in one evaluate.
It errors in the evaulation (not 'at' the evaluation) stating that it was
not expecting the semicolon.
This is different to CF4.5 where you could combine multiple expressions.
cfscript
fff = myNewVar;
evaluate('#fff# = 1; #fff#_another = 2;');
WriteOutput(myNewVar = myNewVar brmyNewVar_another = myNewVar_another);
/cfscript
Anyone seen this before, I was unable to find references to this bug
from googling and direct searching at macromedia.

logic in CFC vs Java CFX
Hi All, I have a Custom CFX Tag written in java (in house) and have wrapped it's access in a CFC. Because there is also some logic in the CFC before it calls the custom tag, should i just ditch the CFC and transfer the logic to the CFX ? Will I gain in performance (yes I am trying to write both but there is actually lot of leg work for this one)? (my understanding is the CFC gets compiled to Java Bytecode) My concern is memory usage and such. The custom tag (Java CFX) scales well handling well over 200 hits per second from varying clients and random data. Is very thread safe. However from my initial development, I can't say the same for the wrapper to the CFX. I managed to lock up the CFMX server with simlilar stress testing to the CFC. The CFC is called via cfinvoke (im moving it to application scope with a cfobject and then inidividual calls to that object) any suggestions, anybody done much work in this area ? cheers - NOTICE - This message may contain confidential, proprietary or legally privileged information and is intended only for the use of the addressee named above.

objects in application memory
We have an application which uses an object in generating page output every request. eg: cfset somevar = myobj.function(param1, param2, param3) I have rewritten it just now as a CFC (originally Java) and plan to invoke it via CFObject. It is generally called upon about 5 times within a page request to do some processing My question is, We will be calling it within the application.cfm so should it be 1) invoked once and loaded into application memory 2) invoked once per session and saved into session memory 3) invoke and use each page request Just wondering if using / storing an object in memory vs invkoing it upon each request has benfits. Dos MX do object caching behind the scenes? Im am assuming depending on Java vs some other type of object .. it should be done differently? Does anyone have any war scars in this area ? What if the CFC was instead a Java Object ? (the current 4.5 site is a Java Object, thread safe and invoked each request) (3 years ago, it was written as a singleton class but CF4.5 didn't like that / didn't seem to work that way so we just made it thread safe.)

RE: Writing Query Results to a CSV using CFFILE
Just saw bug in my code re: the location of a newline. change cfset outputLine = outputLine chr(13) #ID#,#FirstName#,#LastName#,#Address1#,#Address2#,#City#,#State#,#Zip# to cfset outputLine = outputLine #ID#,#FirstName#,#LastName#,#Address1#,#Address2#,#City#,#State#,#Zip# chr(13) and the cffiles to cffile action=append file=#exportFilePath# output='#outputLine#' addnewline=no With regards to building the CSV string in memory. As we found, it absolutely killed poor old CF4.5 and thus my solutions was stream it as much as possible. Your issue (since SQL 7 is purring as it should) is CFFILE. As Barney and Dave mentioned, reducing the CFFILE's would be your goal and I would caution holding the whole string in memory as that too produced a bottleneck for us.

This is the code used to build the file: cfset export_header=Record ID,FirstName,LastName,Address1,Address2,City,State,Zip !--- export table header --- cfoutput cffile action=write file=#exportFilePath# output=#export_header# addnewline=yes /cfoutput !--- append the search query to the file --- cfoutput query=online_reg cfset outputLine=#ID#,#FirstName#,#LastName#,#Address1#,#Address2#, #City#,#State#,#Zip# cffile action=append file=#exportFilePath# output='#outputLine#' addnewline=yes /cfoutput I've tried building one big variable and appending that all at once instead of appending each record one at a time and that takes about twice the time to execute that this code does. I'm beginning to wonder if CFFILE is the best way to go. Any other ideas? I'm running ColdFusion 4.5.

RE: administrator wont open
Sounds like the .cfm{l} file is not registered in Apache to be handled by ColdFusion
(CFMX install should have done it)
What are the contents of the file if you _do_ save it ? Is it the ColdFusion
file ?
Does a normal coldfusion page work (not just admin)
try a simple .cfm page in the root of the server
cfset fff = foobarcfoutput#fff#/cfoutput
If normal cfm pages don't work
take a look in the httpd.conf file looking for the .cfm extension (should be
in there)
the httpd.conf file should be/could be located at /etc/httpd/httpd.conf or
/etc/apache/httpd.conf

Subject: administrator wont open
Hello all. I have recently installed CFMX on Apache
2.0.44 and Apache seems to start fine. All the CF
services are running, but I can't seem to open the CF
admin page successfully. Instead, I am promped to
open or save the cfm file and never get to see the
admin page. I am missing something
simple. Any suggestions??? Thanks in advance.
Juan

RE: administrator wont open
Looks like it didn't install properly.. is Apache in a standard location ? Is there two Apache Servers on the box ? One last thing would be to checkfor the existence of 'coldfusion' in the httpd.conf file. Some examples of configs I have seen don't have .cfm mentioned. In this situation I would opt for attempting a reinstall (making sure that you put Coldfusion into the same path, but check the webserver/apache settings as you go. If you want to try an 'patch it up manually' you could (if it doesn't work, i'd reinstall as CFMX should do this and since it didn't I would suspect, as evident, that it's not installed correctly :-) 1) In the httpd.conf file Add the ColdFusion Module stuff as per : Configuring Apache we server on UNIX section in http://ssis.lbcc.cc.ca.us/cfdocs/Installing_ColdFusion_MX/configuring4.html Where the other 'LoadModule' bits are. Not sure if ports would be the same, change the paths as appropriate 2) add a cfm (and cfml handler) .. can't find a 'real' example but it looks like you need to add AddHandler jrun-handler .cfm .cfc .jsp .cfml .jws into the ifmodule ../ifmodule section (just after the commented out 'jrunconfig Errorurl' bit. otherwise, go for reinstall :-) -Original Message- From: Juan Nava [mailto:[EMAIL PROTECTED] Sent: Wednesday, 12 March 2003 3:17 PM To: CF-Talk Subject: administrator wont open If I choose to open it, Dreamweaver opens it successfully but shows a bunch of junk basically. Anyother cfm page on my machine wont open in the browsers. If I save it, its just like moving the index.cfm file from the original folder to whereever I save it. The httpd file contains nothing menitoning cfm. ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Get the mailserver that powers this list at http://www.coolfusion.com Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
